Anyone know of a chip/board design that has more than one ARM Cortex-M4 or M7, I need 4 of them to do serious signal processing, paired with a big brain like Cortex-A7 that runs linux to send the data to the cloud... ideally would be able to share flash

Hi @CLove.1​ ,

Please consider the STM32 Portfolio on st.com to analyze if a STM32 cluster board can be a solution.

For sure, STM32MP1 can be the Cortex-A7 that runs linux part.

Maybe worth also to consider those 2 links for signal processing on STM32

Hope it help

Yeah, already know about the signal processing libraries, thanks, it is the advanced SIMD stuff on Cotrex-M4 and M7 that I'm using - I just have a lot of signal processing to do requiring 4 cores. I see so many chips that have quad-core A7 for the main OS (linux) and only 1 Cortex-M4 which is odd, why not dual-core-A7 + dual-core-M4, or quad core A7 + quad-Core M4. The only one I can find with tons of low power signal processing cores is in the Qualcomm snapdragon, but that's way over kill for what I need...
